New to vMix. May very well be a Wirecas converst after today WC 7 upgrade ... :~/

Trying out vMix. Like what I see, but learning curve is slow after 7 years on WC.

Question. I have 3 SD cameras coming in. All working well, and broadcasting to my server incredibly well ... except ... there seems to be a "ghost" image from another camera when live on the other cameras. One camera is (the one creating the ghost image) is aimed up and catching some lights. I can see the "hot spots" of light and bright sections of this camera shot in both of the other camera shots.

Is there a fix for this? It is the only thing holding me back from taking the plunge.

this also happen, when we open a saved project and this project have an ndi input camera in it, it looks ghosty, so we have to re- input the ndi again to the project eaxh time,and apply the imput settings again like possiton and stuff.

MrM1,

Are you able to post a screenshot showing what it looks like?
We haven't seen this before so not sure exactly what might be happening.

Here it is in a YouTube Video. At about 24 seconds in you can see the ghosted image of the lights of one camera input thru on the other camera input. Especially in the darker areas of the second shot.

@ MrM1

Can I ask what monitor you have?
I watched your clip on my iPhone and I couldn't see what you are talking about.
It could be that the iPhone is too small to to see it but I suspect it might be a "burn in" effect on the monitor considering I can't see anything on mine...

EDIT: I see it on my desktop computer LG monitor, still looks like a lingering burn-in to me.
Is it perpetually there or does it fade over time?
What if you move or pan the other camera so the bright spot is in a different location?
